Cyclone separation device

Abstract

The invention relates to a cyclone separating device used in the two-phase current of gas and solid or gas and liquid, characterized in that the inletting section comprises the upper-lower plate with the downdip angle and the negative-positive camber, the central column comprises the upper straight section, the middle contracting section and the lower expanding section. The method is based on the cyclone separating mechanism, making uses of the effect of the separating efficiency exerted by the inletting section, providing the initial condition to the cyclone separating, adding to the central barrel structure and optimized location. All these make the particles with different sizes speeding up accordingly, by which can improve the separating efficiency of all particles.

Description

technical field [0001] The invention relates to a separation device, in particular to a cyclone separation device used in gas-solid two-phase flow or vapor-liquid two-phase flow. Background technique [0002] In the production or process of chemical industry, metallurgy, energy, environmental protection and other industries, separation devices with high separation efficiency are often required to capture solid particles in gas-solid two-phase flow or liquid droplets in vapor-liquid two-phase flow. For example, in catalytic cracking, it is necessary to use a separator to separate the catalyst for recycling; in a circulating fluidized bed boiler, the separator separates a large amount of high-temperature solid materials from the gas flow and sends them back to the combustion chamber to maintain combustion The rapid fluidization state of the chamber ensures the repeated use of fuel and desulfurizer, repeated combustion and reaction, so the performance of the separation device w...

Problems solved by technology

Since the separation mechanism of the cyclone separator is not fully considered in this kind of cyclone separator, the structure of the inlet section cannot fully accelerate the particles of different particle sizes, so that the separation efficiency is affected to varying degrees; the inlet horizontal airflow enters After the cylinder rotates downward, the flow direction changes discontinuously with the structure during this process, which affects the centrifugal force of the particles and reduces the separation efficiency; the shape of the central cylinder does not match the shape of the cylinder and the cone acceleration section so that the particles are separated in the separator. The lower half has greater centrifugal force, so the separation efficiency needs to be further improved
